RETAINING DEVICE FOR PRINTFNG SURFACES.

Application filed February 6, 1911.

Specification of Letters Patent.

Patented July 2, 1912. Serial- No. 606,799.

To all w/zom may concern:

Be it known that I, IIENRY C. OsBoRN, a citizen of the United States, residing at Cleveland, State of Ohio, have invented a certain new and useful Improvement in Retaining Devices for Printing-Surfaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a spring clip adapted to be used in conjunction with series of parallel rails to hold a suitable printing plate thereon. I

The invention is in the nature of an improvement in the clip shown, described and claimed in the application of Ferdinand liohenbergcr, #606,795"), filed February 6, 1911. In that application is shown and in the county of Cuyahoga and side of one wing [the other is greater than the space beclaimed a sheet metal spring clip'having outwardly bowed spring tongues, the clip adapted to be sprung between adjacent rails and serving the double pu pose of preventing shifting of the type lengthwise of the rails and also, if necessary, properly spacing the rails with reference to each other. I have devised an improvement on such clip, perform a third function of securing a printing plate in place without interfering with either of its other functions.

My clip is illustrated in the drawings hereof and is hereinafter more fully de scribed.

In the drawings, Figure 1 is a perspective View of the clip; Fig. 2 is an end View of the same between two type-holding rails shown in section; Fig. 3 is an end view of a type form composed of two lines and a plate held on suitable rails; and Fig. at is a plan of a portion of such printing frame.

In the drawings, 10 represents the clip complete. As shown, it consists of a sheet metal member having an intermediate substantially flat portion 11 on the edges of which the metal rounds downwardly .and then inwardly, as at 12, to points each side of the longitudinal central. plane where these two portions are turned downwardly in outtween the rail heads, while the shortest distance between these outer convex surfaces, that is, at the lower end of the wings, is less than the distance between the rails. Accordingly, the clip may be easily placed with its free ends between the rails and then an inward pressure may spring those ends inwardly enough to allow the clip to pass into the position shown in Figs. 2 and 3. In this position the convexity of the wings engaging the inner corners of the rail heads effectively holds the clip in place. iVhen the clip is in place, as shown in Figs. 3 and 4, its tongue 15 may overhang the printing plate, as 32, and securely hold the same on the surface of the rails. The parts may be very easily dimensioned to accomplish this. The printing less height than the plate proper and the clip is made so that the projecting tongue may lie over and in contact with this margin. This obtained by reason of the space 16 between the under surface of the intermediate po rtion 11 of the clip and the upper surface of the portions 12. In addition to this plate holding effect, my clip is shown in Figs. 3 and i as acting also as a stop for the lines of individual type. In this case the clip is conveniently turned so that. the tongue 15 projects 'awa y from the type. In such position, this tongue forms very convenient means for removing the clip, either with the finger nail or any suitable tool inserted beneath the tongue. llhether the clip is used with its tongue holding the plate, as shown in the upper portion of Fig. -jl, or'wit-h its tongue as a removal handle, so to speak, the clip also perform-s the function ofprop erly sparing the rails, when they are not rigidly held, and are liableto stand too close to each other or too far apart.

Reference should be made to the application of Ferdinand Hohenbergcr, heretofore referred to and filed concurrently herewith,

for claims on the clip without limitation.

to the lip 15. The present invention is intended to cover such 11p," both when einbodied in a clip in the specific form shown plate has a margin 31 of I and also when carried by any other struc ture adapted to beclamped between the adjacent rails,

. Having thus described my invention, what I claim is :v

1, The combination, with rails and a printing plate adapted to rest on the surface thereof, of a clip havinga head, and a pair of tongues connected with the head and free at their opposite edges and adapted to elastica-lly engage adjacent rails, there being a lip projecting from the end of the head adapted to overhang the plate.

.2: A clip for use between parallel rails and adapted to hold a printers plate on the surface of the rails, said clip having an intermediate portion, the two portions bent backwardly from the edges of the intermediate portion, the backwardly bent portions and the intermediate portion being spaced apart, a lip projecting from the intermediate portion in the plane thereof and adapted to overhang a plate-when the backwardly bent portions rest on the surface of the rails, and retaining tongues projecting from the backwardly bent portions.

3. 'A clip comprising an intermediate portion, two portions bent backwardly from the edges of the intermediate portion, twolongitudinally straight tongues bent from the edges of the backwardly bent portions, and a lip extending from the end of the intermediate portion.

4. A-clip made of a single piece'of sheet metal and bent to make a head composed of an intermediate flat portion, two rounded edges with inwardly projecting portions substantially parallel with the flat portion and spaced therefrom, twotongues projecting from the two inwardly projecting portions respectively and standing side by side, and a lip projecting from the end of the head substantially in the plane thereof.

5. As a new article of manufacture, a spring clip for use between a pair of parallel typeholding rails, said clip being made of a single" piece of sheet metal having a flatintermediateportion, rounded edges, two in wardly projecting portions substantially parallel with the fiat port-ion and spaced therefrom, two tongues projecting from the inner edges of the inwardly projecting portions, and a lip projecting from one end of the flat intermediate portion, said lip being adapted to overhang and engage the flange of a printing plate resting on the surface of rails between which the tongues project.

In testimony whereof, .I hereunto affix my slgnature 1n the presence of two witnesses.

HENRY G. OSBORN.
